- Your Health Story Holds Clues: A personal or family history of breast, ovarian, or related cancers, especially at a young age, are key reasons to discuss genetic testing with your doctor and see if it’s a good fit for you.
- Turn Information into an Action Plan: Your results are the starting point for a conversation with your care team. Work with them to build a personalized plan for screenings, risk-reduction strategies, and potential treatment options based on your unique genetic profile.
What is Genetic Testing for Breast and Ovarian Cancer?
If you or a loved one has been diagnosed with breast or ovarian cancer, you’ve probably heard the term “genetic testing.” It sounds complex, but the idea behind it is straightforward. Genetic testing is a way to look closely at your DNA for specific, inherited changes (often called mutations) that can increase your risk for developing certain types of cancer. Think of it as getting a personalized look at your body’s instruction manual to see if there are any typos that might affect your health down the line.
This kind of testing isn’t a cancer diagnosis. Instead, it’s a powerful tool that gives you and your doctor information about your personal risk factors. Understanding your genetic makeup can help you make more informed decisions about your health, from screening schedules to treatment plans. It can also provide valuable insights for your family members.
The Role of BRCA1 and BRCA2 Genes
You may have heard of the BRCA1 and BRCA2 genes. These genes are some of the most well-known when it comes to hereditary breast and ovarian cancer risk. Everyone has BRCA1 and BRCA2 genes, and their job is incredibly important—they act like your body’s internal repair crew. They produce proteins that help fix damaged DNA and prevent cells from growing and dividing uncontrollably.
When one of these genes has a harmful mutation, it’s like a key member of the repair crew can’t do their job correctly. This breakdown in DNA repair can allow cells to develop genetic errors that may lead to cancer. Having a mutation in either the BRCA1 or BRCA2 gene significantly increases your lifetime risk of developing breast, ovarian, and other cancers. That’s why BRCA testing is often a starting point for understanding hereditary cancer risk.
Exploring Multigene Panel Tests
While BRCA1 and BRCA2 are major players, they aren’t the only genes linked to hereditary cancer. As our understanding of genetics has grown, so have our testing options. Today, it’s common for doctors to recommend a multigene panel test. Instead of just looking at one or two genes, these panels cast a wider net, simultaneously checking for mutations in many different genes associated with cancer risk.
Think of it this way: if a BRCA-only test is like looking for a specific book in a library, a multigene panel is like scanning an entire section for relevant titles. This approach provides a more complete picture of your potential hereditary risk. The CDC explains that these panels can identify mutations in other important genes that might have otherwise been missed, giving you and your care team a fuller understanding of your genetic profile.
How Gene Mutations Can Affect Your Cancer Risk
Receiving a positive result from a genetic test can feel overwhelming, so it’s important to understand what it actually means. A positive result indicates that you have a gene mutation known to increase cancer risk. However, it is not a guarantee that you will get cancer. It simply means your risk is higher than that of the general population. This knowledge empowers you to take proactive steps to manage your health.
Your genetic information also has implications for your family. If you have a specific gene mutation, your first-degree relatives—your parents, siblings, and children—each have a 50% chance of carrying that same mutation. This is why your results can be a catalyst for important family conversations about health. A BRCA gene test, for example, can help your relatives understand their own risk and make informed choices about their health screenings.
Should You Consider Genetic Testing?
Deciding whether to get genetic testing is a personal choice, but it’s one you don’t have to make in the dark. Certain factors in your personal and family health history can act as signposts, suggesting that a conversation with your doctor or a genetic counselor might be a good next step. Think of it as gathering all the pieces of your unique health puzzle. Looking at your family history, your own health journey, and even your ancestry can help you and your care team decide if genetic testing is right for you.
Clues from Your Family History
One of the strongest indicators for considering genetic testing is your family’s health story. If you look at your family tree and see multiple relatives who have had breast or ovarian cancer, especially at a young age, it’s a significant clue. The CDC notes that having many cases of these cancers in your family is a key reason you might be recommended for genetic testing for hereditary cancer. It’s also important to consider cancers in male relatives, like male breast cancer or prostate cancer. Talking with your family members about their health history can feel difficult, but it provides invaluable information for understanding your own potential risk.
Your Personal Health History Matters
Your own health journey is another critical piece of the puzzle. If you’ve been diagnosed with breast, ovarian, pancreatic, or prostate cancer, genetic testing can be particularly insightful. According to the Mayo Clinic, a personal history of these cancers is a primary reason to think about getting a BRCA gene test. The results can do more than just assess your risk for future cancers; they can also play a direct role in your current treatment plan. Knowing if a gene mutation is involved can open up targeted therapy options that may not have been considered otherwise, making it a powerful tool for you and your oncology team.
Why Your Ancestry Can Be a Factor
Where your family comes from can also influence your genetic makeup and potential cancer risk. For example, people of Ashkenazi or Eastern European Jewish descent have a higher likelihood of carrying BRCA1 and BRCA2 mutations compared to the general population. The Ovarian Cancer Research Alliance (OCRA) highlights that testing is especially important if you have this background. If you know your family has this ancestry, it’s a key factor to discuss with your doctor. Some organizations even provide resources and programs for free genetic testing to individuals who are at a higher risk due to their family history or ancestry, making it more accessible to get the answers you need.
What to Expect from the Genetic Testing Process
If you and your doctor decide that genetic testing is the right move, you might wonder what the process actually involves. The good news is that from your perspective, it’s quite straightforward. The journey from providing a sample to getting your results follows a clear path, and knowing the steps ahead of time can help you feel more prepared and in control. Let’s walk through what you can expect.
How a Sample is Collected
The first step in the process is giving a sample for the lab to analyze. This is a simple and quick procedure. Most genetic tests require either a small blood sample, drawn from a vein in your arm, or a saliva sample, where you spit into a special tube. You can typically provide your sample at a doctor’s office, hospital, or a designated lab. Some companies even offer at-home collection kits that are mailed directly to you, which can be a convenient option. Your healthcare provider will guide you on which type of genetic test is being ordered and where you can have your sample collected.
What Happens in the Lab
Once your sample arrives at the lab, specially trained technicians and scientists get to work. Their job is to carefully examine your DNA, looking for specific changes, known as mutations, in certain genes. For hereditary breast and ovarian cancer, they often focus on the BRCA1 and BRCA2 genes. In many cases, your doctor may order a multigene panel test, which is a broader approach that checks for mutations in several different genes at the same time, including BRCA1 and BRCA2. This comprehensive analysis helps create a more complete picture of your genetic makeup and potential cancer risk.
When to Expect Your Results
This is where a little patience comes in. Analyzing your DNA is a detailed and complex process that can’t be rushed, so it typically takes several weeks to get your results back. The exact timing can vary depending on the specific test being performed and the lab doing the analysis. Waiting can feel like the hardest part, but it’s a normal part of the process. Once the results are ready, they will be sent to your doctor or genetic counselor, who will then schedule a time to discuss them with you, explain what they mean for your health, and help you plan your next steps.
Understanding Your Genetic Test Results
Getting your genetic test results back can bring up a lot of emotions. Whether you feel anxious, relieved, or just plain confused, remember that this information is a tool. It’s designed to give you and your care team more clarity so you can make informed decisions about your health. Let’s walk through what the different types of results—positive, negative, and uncertain—really mean for you and your family.
What a Positive Result Means
Receiving a positive result means the test found a specific change, or mutation, in a gene that is known to increase the risk of hereditary breast and ovarian cancers. While this news can feel heavy, it’s also incredibly powerful. This knowledge allows you to be proactive about your health. You can work with your doctor to create a plan for early detection or take steps to lower your cancer risk. If you’ve already been diagnosed with cancer, a positive result can be a key piece of the puzzle, helping to guide your treatment options and open doors to therapies targeted specifically at your cancer’s genetic makeup.
Interpreting a Negative Result
A negative result can be a huge relief, but its meaning depends on your family’s health history. If a specific gene mutation is already known to run in your family and your test comes back negative for that same mutation, it’s considered a “true negative.” This is great news, as it means your cancer risk is likely the same as the general population’s. However, if you don’t have a known family history of a specific mutation, a negative result is a bit more complex. It means you don’t have the mutations the test looked for, but it doesn’t completely rule out an increased hereditary risk. A genetic counselor can help you understand what a negative result means for you personally.
Decoding a “Variant of Uncertain Significance” (VUS)
Sometimes, a genetic test will identify a gene change that hasn’t been clearly linked to cancer risk. This is called a “variant of uncertain significance,” or VUS. Hearing the word “uncertain” can be unsettling, but it simply means that researchers don’t have enough data yet to classify the variant as either harmful (positive) or harmless (negative). Think of it as a “we’ll get back to you on this” from the scientific community. As researchers gather more information, these variants are often reclassified. Your genetic counselor will explain what a VUS means for your health plan in the meantime and will let you know if its classification changes in the future.
How Your Results Can Help Your Family
Your genetic test results don’t just belong to you—they can be a vital piece of health information for your entire family. If you test positive for a gene mutation, your close biological relatives (like your parents, siblings, and children) have a 50% chance of carrying that same mutation. Sharing this information with them is one of the most important steps you can take. It gives them the opportunity to pursue their own testing for that specific gene change. This knowledge can empower them to make proactive decisions about their own health and screening plans, potentially leading to early detection or prevention. It’s a conversation that can truly make a difference for the people you love.
Common Myths About Genetic Testing, Debunked
When you’re considering genetic testing, it’s easy to get tangled up in misinformation. The topic can feel complex, and there are a lot of myths floating around that create unnecessary worry. Let’s clear the air by looking at the facts behind some of the most common misconceptions about genetic testing for breast and ovarian cancer. Understanding the reality can help you feel more confident and prepared as you make decisions about your health. Getting straight answers is the first step toward taking control of your health journey.
Myth: Most Breast Cancer is Hereditary
It’s a common belief that a breast cancer diagnosis is almost always tied to family history, but that’s not the case. The truth is, most breast cancers are considered “sporadic,” meaning they happen by chance and are not linked to an inherited gene mutation. While having a strong family history of breast or ovarian cancer is a significant reason to consider genetic testing, it’s important to know that only about 5% to 10% of all breast cancers are thought to be hereditary. This is why understanding your personal risk factors, in addition to your family’s health history, is so crucial for you and your care team.
Myth: Genetic Tests are Always Conclusive
It would be nice if every test gave a simple “yes” or “no” answer, but genetic testing can sometimes be more complex. While many people get a clear positive or negative result, some receive a “variant of uncertain significance” (VUS). This means the lab found a change in one of your genes, but experts don’t yet know if that specific change affects your cancer risk. It’s an ambiguous result that can be frustrating, but it’s important to know it’s a possibility. Additionally, it’s helpful to remember that genes like BRCA1 and BRCA2 are linked to an increased risk of several cancers, including ovarian, prostate, and pancreatic cancer, not just breast cancer.
Myth: My Results Could Affect My Insurance
Many people worry that a positive genetic test result could lead to them being denied health insurance or employment. Thankfully, there are legal protections in place. The Genetic Information Nondiscrimination Act (GINA), a federal law, makes it illegal for health insurance companies and employers to discriminate against you based on your genetic information. However, it’s important to be aware that GINA’s protections do not extend to life insurance, disability insurance, or long-term care insurance. Understanding these distinctions can help you make informed decisions before you get tested.
What Are Your Next Steps After Getting Results?
Receiving your genetic test results can bring up a lot of emotions, whether they’re positive, negative, or uncertain. Remember, this information isn’t a diagnosis—it’s a powerful tool. It gives you and your care team the knowledge to create a proactive health plan that’s tailored specifically to you. Think of your results as the first step in a conversation about your long-term health and well-being. The next steps are all about working with your doctor to understand what this information means for you and deciding on a path forward together.
Creating a Plan to Manage Your Risk
If you test positive for a gene mutation like BRCA1 or BRCA2, your first move is to schedule a follow-up with your doctor and a genetic counselor. They are your partners in this process and will help you understand the results in the context of your personal and family health history. Together, you can create a clear plan to lower your cancer risk. This plan might include more frequent cancer screenings, such as alternating between mammograms and breast MRIs. It’s also a good time to discuss whether your close relatives, like siblings and children, should consider getting tested, as they may share the same genetic risk.
Considering Preventive Surgery
For some people with a positive result, preventive (or prophylactic) surgery is an option to consider. This involves surgically removing healthy tissue to significantly reduce the chance of cancer developing. The most common procedures are a prophylactic mastectomy (removal of breast tissue) and a salpingo-oophorectomy (removal of ovaries and fallopian tubes). This is a very personal decision with physical and emotional implications, and it’s not the right choice for everyone. Your healthcare team can walk you through the benefits and risks, helping you weigh this option against other risk-management strategies like enhanced screening or medication.
Developing a Personal Screening Plan
Based on your results, your healthcare team will help you create a personalized screening schedule. This isn’t a one-size-fits-all plan; it’s designed just for you. For example, instead of starting mammograms at age 40, your doctor might recommend starting them earlier or having them more often. They might also add other imaging tests, like breast MRIs, to your routine. The goal is to catch any potential issues as early as possible. Your doctor can also discuss other ways to lower your risk, such as medications that can reduce the chances of developing certain cancers. This personalized BRCA gene test plan puts you in control of your health monitoring.
Partnering with Your Doctor on Treatment
Ultimately, knowing your genetic status helps you and your doctor become stronger partners in managing your health. This knowledge empowers you to make truly informed choices about your care, from screenings to preventive actions. If you have already been diagnosed with cancer, this information can sometimes influence treatment decisions, as certain therapies are more effective for cancers linked to specific gene mutations. By understanding your personal risk profile, you can work collaboratively with your doctor to build a comprehensive health strategy that feels right for you and your life.

Frequently Asked Questions
If I test negative, does that mean I’m completely in the clear for breast or ovarian cancer? A negative result is definitely reassuring, but it’s not a free pass. It means you don’t carry the specific harmful gene mutations the test was looking for. This is great news, especially if a known mutation runs in your family. However, most cancers are not hereditary. Your overall risk is still influenced by other factors like lifestyle and environment, so it’s important to continue with regular screenings and maintain a strong partnership with your doctor to monitor your health.
What’s the real difference between a multigene panel and a test that only looks for BRCA mutations? Think of it like this: a BRCA-only test is looking for two very specific, well-known risk factors. A multigene panel casts a wider net. It checks for mutations in the BRCA genes plus a number of other genes that have also been linked to an increased cancer risk. Your doctor might recommend a panel test to get a more complete picture of your potential hereditary risk, as it can sometimes find answers that a more targeted test might miss.
How do I bring up genetic testing with my doctor without feeling like I’m overreacting? This is a completely valid concern, but remember, you are your own best health advocate. You can start the conversation simply by saying something like, “I’ve been thinking about my family’s health history, and I’d like to talk about whether genetic testing might be right for me.” You can also mention specific concerns, such as a relative’s diagnosis or your ancestry. This isn’t overreacting; it’s being proactive and informed, and your doctor will see it as a responsible step.
My family isn’t open about their health history. Can I still get tested? Yes, absolutely. While a detailed family history is incredibly helpful, it’s not the only reason to consider testing. Your own personal health history, such as a cancer diagnosis at a young age, or your ancestry can be strong enough indicators on their own. Share what you do know with your doctor or a genetic counselor. They can help you determine if testing is appropriate based on the information you have.
What exactly does a genetic counselor do, and why is talking to one so important? A genetic counselor is an expert who acts as your translator and guide through this entire process. Before you even get tested, they can help you decide if it’s the right choice for you. Afterward, they do much more than just give you the results. They help you understand what the results truly mean for your health and for your family, discuss the emotional side of things, and walk you through all of your options for managing your health moving forward.
